Results of primary angioplasty for acute myocardial infarction in patients with multivessel coronary artery disease

Background: Coronary artery disease is a major public health concern worldwide. In Africa, varying rates of progression increased in different countries. In Angola, although the epidemiological scenario is dominated by infectious diseases, the prevalence of coronary artery disease is increasing with notable impacts, requiring the creation of mechanisms to face this reality in a country where lack of specific infrastructure is still a challenge. The objective of this study was to describe the experience of primary angioplasty in patients with acute myocardial infarction in an Angolan tertiary care center. Methods: This was a descriptive, longitudinal, retrospective study, involving 165 patients diagnosed with acute myocardial infarction between 2012 and 2019. Variables were age, sex, risk factors, angiographic and procedure-related characteristics, and main complications. Results: The mean age was 58.3±6.8 years, and males predominated (75.8%). Hypertension (69.7%), dyslipidemia (35.2%), smoking (32.7%) and diabetes (29.7%) were more prevalent. The anterior location was the predominant topography of infarction (49.7%). Single vessel disease was the most common pattern (50.9 %). The left anterior descending artery was the most often involved vessel (49.7%). The door-to-balloon time was 46.6±32.4 minutes. In the multivariate analysis, anterior myocardial infarction (p=0.033), diabetes (p=0.004), age ≥60 years (p≤0.001) and post-coronary intervention final TIMI flow Conclusion: Percutaneous coronary intervention in the context of acute myocardial infarction in Angola is a reality, but the number of procedures performed is not enough given the current great demand.

Abstract Background Clinical benefits of complete revascularization (CR) in acute myocardial infarction (AMI) patients are unclear. Moreover, the benefit of CR is unknown in AMI with Diabetes Mellitus (DM) patient. Objectives We sought to compare prognosis of CR and incomplete revascularization (IR) in patients with AMI and multivessel disease, according to the presence of DM. Methods A total of 2,150 AMI patients with multivessel coronary artery disease were analyzed. CR was defined based on angiographic image. The primary endpoints of this study was patient oriented composite outcome (POCO) defined as a composite of all cause death, any myocardial infarction, and any revascularization within 3 years. Results Overall, 3-year POCO were significantly lower in patients receiving angiographic CR (985 patients, 45.8%) compared with IR (1165 patients, 54.2%). When divided into subgroups according to the presence of DM, CR reduced 3-year clinical outcomes in the non-DM group but not in the DM group (POCO: 11.7% vs. 23.2%, p<0.001, any revascularization: 7.2% vs. 10.8%, p=0.024 in the non-DM group, POCO: 24.3% vs. 27.8%, p=0.295, any revascularization: 13.3% vs. 11.3%, p=0.448 in the DM group, for CR vs. IR). Multivariate analysis showed that CR significantly reduced 3-year POCO (HR 0.52, 95% CI 0.38–0.71) only in the non-DM group. Conclusion In AMI patients with multivessel disease, CR may be ineffective in improving clinical outcomes in patients with DM. Funding Acknowledgement Type of funding source: None
